The virtually worldwide family Syrphidae, commonly called flower flies, consist of moderately-sized flies with often striking color patterns. There are approximately 6,000 described species in almost 200 genera. Adults of extant forms are often found hovering around or feeding on flowers. Some are important pollinators of various flowering plants. Larvae occupy diverse habits. Species of Microdontinae are known only from ants nests. Larvae of other subfamilies are either predaceous on other invertebrates, scavengers, or mycophagous or phytophagous. Larvae of some Eristalinae are known to be associated with tree holes and ulcerated wounds making them susceptible to being trapped in resin flows. This may explain the relative frequency of Eristalinae as inclusions in amber.
In addition to the determined forms listed below, Schumann &
Wendt (1989: 42) recorded undetermined material of this family
from the Miocene Bitterfeld amber deposits of Germany, Wilson
(1977) recorded the family from the Middle Eocene deposits of
British Columbia (making that material the oldest representative
of the family in North America), and Kovalev (1979) recorded what
may be the oldest example of the family from the Cretaceous resins
of the Taimyr in Siberia.
